JOHN W. BRAY, OF LEEDS, ENGLAND.

ATMOSPHERIC BURNER FOR INQANDESCENT GAS-LIGHTING.

SPECIFICATION forming part of Letters Patent No. 755,213, dated March 22, 1904.

Application filed July 14, 1903. Serial No, 165,505- (No model.)

T0 (.LZZ whom, it may concern/.-

Be it known that I, JOHN WILLIAM BRAY, a subject of the King of Great Britain and Ireland, residing at Leicester Place, Leeds, in the county of York, England, have invented certain new and useful Improvements in Atmospheric Burners for Incandescent Gas- Lighting, of which the following is a specification.

This invention is for an improved atmospheric burner for incandescent gas-lighting, and has for its object the construction of an incandescent gas-burner so as to secure, first, economical consumption of gas; second, simplification of construction; third, improved facility for attaching an ordinary household globe-holder to the burner in place of or in addition to the usual chimney-gallery; fourth, obtaining a better mixture of gas and air and producing a practically silent burner.

In describing my invention indetail reference is made to the accompanying sheets of drawings, similar letters indicating similar parts, in which Figure 1 represents an elevation of the complete burner. Fig. 2 represents a sectional elevation of the upper portion of the burnertube with the burner-head in position thereon.

parts of the burner.

In carrying out my invention I construct the upper portion A ofthe burner-tube of suitable metal, having by preference a coneshaped portion, as shown in Figs. 1, 2, and 4. Such tube may be threaded internally toward the bottom in order to screw onto the lower burner-tube B, which may be threaded for some little distance for this purpose on the outside, as shown at C, Fig. 7 or such tube A may fit onto C without being threaded, in which case the portion C is made rather longer and split at C as shown in Figs. 10 and 11. Directly below the threaded portion 0 of tube B the diameter is increased, so as to fit an ordinary globe-holder, and threaded at C for the reception of a gallery D, Fig. 5, or an ordinary globe-holder. 'The'diameter of the lower portion B of tube'B is further increased, as shown in Fig. 7 and two or more holes E The wind-guard F is cone-shaped, formed substantially as shown in Figs. 1 and .6, and is threaded internally at the top and is attached to the tube B by screwing onto the threaded portion C. Besides being a windguard it is made to form an efiicient stand for the burner when removed from the gas-inlet.

The gallery D is screwed onto the threaded portion C of tube B and the tube A screwed or placed onto portion C. The lower portion of tube B fits onto the gas-nipple G, which is rather larger than hitherto, as shown in Fig.

8. The said gas-nipple Gr may be attached to the gas-supply pipe by the adapter H in the ordinary manner. I

The burner-tip J may form part of the upper burner-tube A; but I prefer the same separate, as shown in Fig. 3, the tip J being held in a suitable metal socket K, which may fit into or around the upper portion of tube A. Springs L may be formed in such upper portion, as shown in Figs; 2 and 4:, for the purpose of holding socket K firmly in position.

The burner is formed of a steatite, porcelain, or similar non-corrosive tip J, having holes 0 substantially of the form shown in Fig. 9, and is provided with a wire-gauze diaphragm M immediately under and in contact with the tip and also with another diaphragm, N, of wire gauze, leaving a space between the two diaphragms, but by preference fixed on or near the shoulder of the tube A, as shown in Fig. 2. The combination of these three elements produces a practically silent burner.

The cone-shaped portion F may be formed, as shown in Fig. 10, with the open portion at the base closed by a plate 0, leaving a hole through the center of same, the edge of such hole being turned up, as at Q, to form a hearing for the gas-nipple G. Holes R are formed in said portion F for the admission of air, and the tube B is not continued to the bearing Q, but terminated below the screwed portion C, as shown in Fig. 10.

The cone-shaped portion F may be formed as shown in Fig. 10 and the tube B, Fig. 11, formed rather longer than shown in Fig. 7 and holes E formed therein, such holes being larger than those shown in Fig. 7. The plate 0 is fitted to the base of portion F, as before described, such portion F having air-admission holes R, as shown in Fig. 10, the hole I being formed in plate 0; but the edges of same are not turned up to form a bearing for the nipple-carrier, the lower portion of tube B below the holes E forming such bearing, Fig. 11. The gas-nipple G in the nipplecarrier is by preference sunk, as shown in Figs. 12 and 13.

\Vhat I claim as my invention is- 1. In an atmospheric burner for incandescent gas-lighting, the combination of the upper part A, having an enlarged end and carrying a tip and having its lower end internally screw-threaded, a tube B screw-threaded externally at its upper end and screwed into the lower end of the upper part A, a gallery D screwed onto the tube B and extending upwardly and a guard F screwed onto the tube B and extending downwardly from its point 20 of support, the ends of said guard projecting down to a point flus'h with the end of the tube B, substantially as described.

2. In combination with a tubeA having its upper end enlarged, a gauze screen therein, a holding-socket K removably fitted to said tube, a wire-gauze screen carried by said socket and a tip also carried by the said socket, the said screens having a space between them and clips for holding the socket to the tube, sub- 3 stantially as described.

In witness whereof I have hereunto set my hand in the presence of two Witnesses.

JOHN \V. BRAY.
